A vacuum suspension system includes a rigid socket defining a socket wall having exterior and interior surfaces. The socket defines an aperture extending between the exterior and interior surfaces, and has a closed distal end and an open proximal end with an interior cavity defined by the interior surface. A fluid regulator is provided at the aperture and operatively engages the fluid regulator. A pump system includes a pump and a covering for securing over the exterior surface of the socket and carrying the pump. The pump is configured for placement proximate to the fluid regulator and arranged for drawing air from the socket through the aperture. A chamber having a variable volume is formed by a space defined between the exterior surface and an inner surface of the covering proximate to the pump.
